(CBS) Music artists continue to mourn late singer Whitney Houston, who died Saturday at the age of 48.

Dolly Parton said she was brought to tears after Jennifer Hudson's Grammy performance of "I Will Always Love You," a song she wrote and recorded in 1973.

"Like everybody else, I am still in shock," Parton revealed. "But I know that Whitney will live forever in all the great music that she left behind. I will always have a very special piece of her in the song we shared together and had the good fortune to share with the world. Rest in peace, Whitney. Again, we will always love you."

As for Hudson, she spoke up about what it was like to pay tribute to Houston at the Grammy Awards a day after her death.

"It was the greatest honor of my life to be able to be the one to pay tribute to Whitney's memory," Hudson, 30, told Us Weekly. "It was from my heart. I haven't stopped crying since she passed. Her family is in my prayers."

Other stars continue to pay their respect to the late singer. Paul McCartney and his wife Nancy Shevell were photographed leaving a bouquet of yellow roses outside the Beverly Hilton hotel on Monday. While there, they chatted with fans about Houston and her music, reports TMZ.
